The task asks to list the numbers in order from least to greatest. The given numbers are:

$\sqrt{5}, 3.7, \frac{1}{2}, -4$

Step 1: Approximate the values

1. $\sqrt{5} \approx 2.236$
2. $3.7$ (already in decimal form)
3. $\frac{1}{2} = 0.5$
4. $-4$ (already in integer form)

Step 2: Arrange the numbers

Now, let's compare these values:

• $-4$
• $0.5$
• $2.236$
• $3.7$

Final Order:

From least to greatest, the numbers are: $-4, \frac{1}{2}, \sqrt{5}, 3.7$
